Application filed April 11, 1914. Serial No. 831,111.

To all "whom it may concern Be it known that I, Josnrn L. POTTER, a Citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Excavating-Bucket, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to excavating and hoisting apparatus, more particularly to the type illustrated in my-pending application for Letters Patent of the United States filed December 11, 1913, Serial No, 805,800, the invention having reference more particularly to an excavating bucket adapted to be operated and controlled by various means, more especially as described in said application for Letters Patent which shows and describes various features of the present invention.

An object of the invention is to provide an in'iproved excavating bucket that shall be so constructed as to be adapted to be operated and controlled economically and especially adapted to quickly discharge its load after having been hoisted. v

A further object is to provide an improved dumping drag bucket or scoop that shall be capable of operating in hard or stony ground and expeditiously, and which when operating in soft or muddy ground shall be capable of quickly discharging its load freely and without liability of sticky ground to adhere and prevent free discharge of the load.

A more specific object of the invention is to provide an improved excavating bucket or shovel which may be constructed principally of standard merchant bar and sheet stock of iron or steel and require the minimum amount of machine Work and also forging in the construction thereof, and- Referring to the drawings, Figure-1 isa perspective view, partially broken away, of the improved excavating bucket in one of its more simple forms; Fig. 2, a fragmentary section showing details of a cutting or (ligging tooth with which the bottom of the I bucket preferably is provided; Fig. 3, a fragmentary section approxunatcly on the plane of the line A A in Fig. 1; Fig. l, a fragmentary scct 1on sumlar to Fig. 2, but

with the tooth omitted, being approximately on the line B B in Fig. 3; Fig. 5, an inverted plan of the bottom of the bucket as preferably constructed and other features of the improvement, portions of the bottom being broken away; r 1g. 6, a fragmcntarv side elevation of the improved bucket slightly modified as to contour; Fig. 7, a perspective view of the improved bucket in a more simple form; Fig. 8, a fragmentary section approximately on the line C U in Fig. 7; Fig. 9, a fragmentary perspective view showing details of the sectional bottom of the bucket; Fig. 10, an inverted plan of the body of the bucket as shown in Fig. 7; Fig. 11, a fragmentary section on the line D I) in Fig. 10: and Fig. 12, a section on the plane ofthe line E E in Fig. 7 omitting the hail of the bucket.

Throughout the various figures of the drawings, similar reference characters indicate like elements or features of construction herein referred to.

The improved bucket is adaptable with slightmodification for use under various conditions, it being understood that conditions are different in different localities Where excavations are required, especially in making excavations for sewers. As prefera-blyconstructed the bucket has a sectional bottom which comprises a suitable number of longitudinally arranged main sections 1, 2, 3, each being composed of channel-iron or steel, and other relatively narrower filling sections 4, 5, 6, 7 suitably secured to the main or channel-iron sections in such manner that the top or upper side of the different sections are all on one and the same plane, the flanges 8 and 9 of the channel sections being under-most. In some cases the filling sections are composed of channeliron or steel of suitable dimensions and arranged with their flanges 10 and 11 undermost, the webs of all the sections being arranged on one and the same plane, some of the filling sections being placed between two of the main sections, as shown there being also a filling section on the outer side of each outer-most main section, each two adjacent flanges of the sections being firmly secured together by means of rivets 12. In some cases the filling sections are devoid of flanges and are secured to the flanges of adjacent main sections by means of rivets 13. The filling sections are preferably shorter than the main sections and arranged so that they do not extend as far forward as the main sections, leaving spaces in which digging or cutting teeth 14, 14, 15, 15 are inserted so as to formcontinuations of the filling sections, the teeth-projecting forward farther than the main sections, the middle teeth preferably projecting farther than the remaining teeth. The tops of the teeth are preferably on one and the same plane with the main sections, and the ends or forward portions of the teeth are beveled on their upper sides. Two sides 16 and 17 are composed of sheet metal and are secured to the outer sides of the two outer-most sections 4 and 7 respectively by means of rivets 12 engaging the flanges of the sections, or longer rivets 13 extending through the sections and engaging the adjacent flanges of the main sections of the bottom. Each middle or intermediate tooth is secured to the flanges of. the adjacent main sections by means of suitable devices such as bolts 18 and 18, so as to be removable if desired, the side teeth being secured to a flange and also to the side of the bucket by means of bolts 19, 19', and 20, 20 which also secure side cutting teeth :21 and 22 to the outer sides of the sides 16 and 17 respectively. The bottom teeth preferably are adjustaliile so that their points may be raised or lowered. each tooth having holes 23, 23', and the bottom sections having holes 24, 24 to which the bolt 18 may be transferred. as shown more clearly in Figs. 2 and 1: or the bolt 18' may remain in one position, the tooth having holes 25 and to which the bolt 13 may be transferred when the tooth is adjusted, as indicated in Fig. 11. Preferably two of the bottom sections 5 and G are longer than the remaining filling sections and they project rearward so that their end portions constitute hinge members 96 and 26 provided with hinge pins 27 and 27' re' spectively, in case the bucket is intended to dump its load when in suspended position.

In case the bucket is intended to be used for hoisting and dumping free-running earth the bucket body is provided with a cover or top 28 which may be formed in tegrally with the sides 16 and 17 if desired, it being preferable that the inner side of the bucket be free from obstructions tending to retard the discharge of the load. Preferablv the bucket is provided with an end gate or door 29 composed of sheet metal and provided with hinge members 30 and 30 which are connected to the hinge pins :27 and 27' respectively, the gate being provided also with curved bars or members 31 and 31 which preferably are secured to the hinge members of the gate and have convex outer faces, portions of the faces being approximately concentric and the lower portions eccentric to the pivots of a controlling bail for the gate to be further described, the gate being provided with a suitable stop bar 32 which preferably is secured to the members 31 and 31 so as to limit the upward movement of the bail. In some cases the gate 33 is curved, the rear ends of the sides of the bucket being correspondingly curved, the door being provided with a curved hinge member 34 having a stop device 35 formed thereon, as seen in Fig. 6. It will be understood also that in some cases the bucket may be devoid of a cover or top and may have a rear end 86 suitably connected to the sides 16 and 17 and also fixedly secured to the sectional bottom by means of an angle member 37. as shown in Figs. 7 and 12. It will be understood that the gate 29 may be variously controlled or secured in closed position.

In order to expeditiously control the hinged end gate the sides 16 and 17 are provided with pivots 3S and 38 respectively to which a suitable controlling bail is connected. The bail preferably comprises two arms 39 and 40 that are connected to the respective pivots and are bent over each toward the other so as to form cross-bar portions 411 and 42 adapted to engage the members 31 and 3,1, and also handle members 43 and 44 that are suitably secured together. The bail is preferably provided with a runner 45 adapted to slide on the bottom of the trench when the bucket is dragged, so as to carry the bail and retain the cross-bar in contact with the members 31 and '31 to hold the. gate in closed position. the bail being per mitted to swing slightly on its pivot, however. and being limited in its upward movement by contact with the stop bar 32. Preferably the arms 39 and 40 are provided with lateral fingers 46 and ll respectively that extend beyond the plane of the tops of the sides 16 and 17 of the bucket, the fingers the flanges of the sections being in contact with the flanges of adjacent sections and rigidly secured together, two body sides on the two outermost ones of the sections respcctivel and rigidly secured to the outer- 8.

14:. In an excavating bucket.,the combina tion with two sides, of a bottom con'iprising a plurality of main sectionshaving'each .a

plurality of flanges on the underside thereof, a plurality of filling sections between the main sections and fixedly secured to the adjacent flanges thereof, and a plurality of teeth between the niainsections at the forward ends of the filling sections and secured to the flanges of the main sections, said bottom being secured to the two sides.

15. In an excavating bucket. the combination of a plurality of main bottom sections,

a plurality of relatively shorter filling sections bet-ween the main sections and secured thereto, a plurality of teeth, between the main sections at the forward ends of the filling sections and secured to the main sections, two filling sections secured to the I outer ones respectively of the main sections,

two sides secured to the two filling sections respectively, and two teeth between the sides and the outer ones of the main sections and secured thereto at the forward ends-of the two filling sections respectively.

16. In an excavating bucket, the combination of two normally upright separate side members, a plurality of normally horizontal bottom sections longitudinally arranged side by side and between the lower portions of the side members. each section comprising aweb and two downward extending flanges. one fiange being in contact with one flange of the next adjacent section and secured thereto. the outer flanges of the outer sections being secured directly to the lower portions of the side members respectively. and cutting teeth arranged adjacent to the forward ends of a number of the ections and secured thereto.

17. In an excavating bucket, a bucket bottom comprising a plurality of normally horizontal sections arranged side by side, the sections each having-two downward extending members. horizontal devices securing :nliacent members together, and teeth secured between, and'to the downwardextending members, incombination with two being so arranged as to swing the bail to release the end gate when the bucket is hoisted so that the fingers are moved into contact with a suitably supported object. The controlling bail may be itself controlled by means of a cable connected thereto.

The bucket is provided with a suitable bail for dragging or hoisting the bucket, and preferably the sides 16 and 17 are provided respectively with pivots 49 and 49, the bail preferably comprising ,two channel section arms or side bars 50 and 50 connected at one end to the pivots, the opposite end being provided with a compound cross-bar comprising two channel section bars 51 and 51' secured to the arms by means of angle braces or knees 52 and 52 an e e- )late 53 bein 7 11 inserted between the bars and secured thereto and adapted to be connected to a cable, whereby the bucket may be dragged in operation or hoisted for discharging the load from the bucket. Preferably the bail is secured against pivotal movement by means of bolts 55 and 55 securing the arms of the bail to the sides of the bucket, the sides having suitable holes 56 and 56' to which the bolts maybe transferred in order to adjust the position of the bail relative to the bucket, either for deep or relatively shallow digging, as may be required.

It should be understood that various modifications other than those particularly pointed out, especially with reference to various details of construction, may fairly be made within the scope of the appended claims.

In practical use, after having adjusted the angle of the digging or scraping teeth of the bottom as may be desired for the particular work to be done, the bucket is drawn backward by means of the controlling bail when the bucket is equipped with the bail, or when using the simple form of bucket shown in Fig. 7 the bucket may be placed in position in various ways and is drawn forward to force the teeth to loosen the earth so that the bucket becomes filled. and the load may be variously disposed of as may be required. When the bucket is equipped with the hinged nd gate and controlling bail, when the mckct is drawn forward the runner 45 slides 11'] the ground andprevents the gate from iwinging open. The bucket may be hoisted y means-of a cable suitably controlled, and lllC fingers 4G and 47 or other portion of the ear bail may be suitably engaged and moved ;o as to cause the controlling bail to swing may from the end gate. so as to quickly cleanse the load. 01'. after the bucket is ioisted. the controlling bail may be caused o swing by various means so as to permit he end gate to swing open. After the load |as been discharged the controlling bail is )ermitted to swing by gravity to n 'rmal iosition, so that the cross-bar of the bail engages the end gate and moves it to closed position to be retained by the bail while the bucket is again placed in position and reloaded as before.
